Munster have named an unchanged team for their crunch Champions Cup clash against Castres in Thomond Park on Sunday (KO 1pm).

Johann van Graan will stick to the 15 who suffered an agonising late 34-30 defeat against Racing 92 last week knowing a bonus point win over Castres will be enough to ensure they will finish top of Pool 4.

As reported by Independent.ie this morning, it is Ross Byrne and Jamison Gibson-Park, not Jonathan Sexton and Luke McGrath, who will guide Leinster into battle against Montpellier at The Altrad Stadium tomorrow (KO 1.0, Sky Sports Action).

Wallaby Scott Fardy is the 'non-European' player to lose out as James Ryan and Jordan Larmour, on the wing, will have the chance to show Joe Schmidt they are ready to play a part in the Six Nations.

Ulster, meanwhile, have made three changes to the side who beat La Rochelle last weekend for Sunday's game with Wasps (KO 3.15) with Darren Cave, Kieran Treadwell and Kyle McCall all included.
